hi I have taken one image control("image1") in the form("frmForm1.aspx").Now i want to one image ("mypic.jpeg") whose size is larger than the image control i.e image1.When i run the program, the image control takes the size of the image mypic.jpeg.But what i want is that the image mypic.jpeg fit in the image control along with its size.I mean the image mypic.jpeg should expand if it's size is smaller than image control and should contract if it's size is larger than image control.But the size of the image control shouldn't be changed. So, how can i do this ??? Currently, i am using ASP dot net 2005 using C# dot net ..

Have you set the Width and Height property of the Image control?

Hi frds pls solve my doubts and reply back with your valuable answers

1.Difference between container.dataitem() and databinder.eval(),Eval() ?
2.Where garbagecollection starts in .Net? How garbage collector know which objects are no longer refered?
3.If we create more non clusteredindexes then what will happen is it advantage or disadvantage?
4.Difference between response.clear and response.flush()?
5.class a
{
method a()
{}
}

class b:a

{
method a()
b ob=new b();

The problems are these:

If you both don't know this stuff, and don't know enough about using the web to find the answers, then no matter what answers we give you, you won't pass your interviews due to other questions you get asked.

So many people make the mistake of thinking if they can fudge the interview, that's what matters. Knowing your stuff is what matters, and these are basic sort of questions.

First one clears the buffered HTML. It won't clear the headers. Later send buffered output immediately

Google for how objects are stored in memory before you go for garbage collection

Why don't you write an application and experiment this ?

Hi,
I want to draw lines on GridView control in asp.net 2.0. I know that drawing lines is now easy with the Drawing namespace. My actual problem is to convert already rendered grid view to an image and then draw lines on that image.
This should be possible in some way, I think. Can any one of you guide me in this regards.

Thanks !

You don't want to do that. You want to make the gridview owner drawn and then draw the lines directly onto the control. Otherwise, none of your control will be interactive, you'll just be showing a bitmap.

Hi Christian,
Thanks for the reply, first. What I want is to draw lines between some of images which are already in the GridView control. No matter it is in bitmap format. I only want to make it visible and then print the image. Actually, there will be a button to generate this image on fly.
Hope you got me. Any links will be appreciated.

Thanks !

Hi friends,
can you please tell me whether there is any control/tool available for asp.net where whatever i will write/paste that will be stored in data base in the same format.Suppose i am pasting one table inside that then i should be able to get the table exactly same.The tool will be very much similar to the editor we use in this site for posting questions and answers.

You can hook up controls to automatically do that, but no-one does that if they are writing real software. They have a proper data layer which they call with those values.

EXE file of ASP.NET application ?

ASP.NET application won't make any EXE file. Do you mean invoking another EXE file ?

ASp.NET runs on the client machine, so your exe won't be there, and in any case, a web page can't launch other programs, that would be a security nightmare.

Datatgrid/Label will render the contents as plain HTML. When you type on textbox, it will have newline characters (\n). This won't be rendered correctly. That is making problem. So you need to replace \n with <br> to show the details correctly.

Can you post the code?
Just the part where you are assigning the dataset to the datasource and binding it.

DateTime Conversion error

Gymnast30-Sep-07 9:18

30-Sep-07 9:18

I am trying to retrieve the time from TableB into TableA. All it does is post the current date in the format...9/30/2007 0:00:00

What I am looking for is the time value in TableB.

Here is my code..

<pre

scmd.commandtype =="" commandtype.storedprocedure

="" scmd.parameters.add("@scheduleddate",="" sqldbtype.datetime).value="CDate
(startDateTextBox.Text)

" scmd.parameters.add("@starttime",="" "long="" time")=""

'tried="" convert.todatetime(startdatetextbox.text)...didn't="" work...

pre="">

I have made sure the datatypes in the SQL Server database matches in both the Tables.

Let me know why this is failing.

Thanks,

Gym

What is the value of startDateTextBox? Does it contain a full date and time?

You might be better off storing the entire thing as a single column that holds both the start date and time or storing just the start date and the time as an offset from midnight.

What was the error you got when you tried the Convert.ToDateTime call?

Scott.
